Application aiea apra is, 1917. serial no. 162,986.

To all whom it may concern Be it known that I, ROBERT PonLsoN, a citizen of the United States, residing at Hutchinson, in the county of McLeod, State of Minnesota, have invented certain new and useful Improvements in Fail-Cover Attachments; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

This invention relates to covers for cans or pails.

The object of the invention is to provide a suitable attachment Jfor the covers of pails, cans and similar receptacles. More particularly it is an object to provide a closure attachment which may be securely and quickly closed to prevent the contact of the atmosphere with the contents of the vessel, 'the closure combiningv the attributes of simplicity and economy of manufacture.

It is furthermore the object of the invention to provide a combined spout and closure in which the closure is resilient locked in its closed position but does not require the manipulation of a particular locking device in order to release it from its closing position. l

With the above and other objects in view, and such others as may hereinafter appear, my invention will now be fully set forth and described, reference being had to the accompanying drawings.

In the drawings Figure 1 is a plan View of a cover having my attachment applied thereto,

Fig 2 is a section on line 2-2 of Fig. 1, showing the closure open and,

Fig. 3 is a section on line 3-,3 of Fig. 1,.

Fig. 4 is a. section on line 4-4 of Fig. 1. Referring more particularly to the draw ings 1 indicates a cover of a bucket or can within which is formed an outlet opening 2, the opening being located to one side of the center.

Disposed around the outlet end of the opening and extending along its longitudinal sides is the wall structure 3 the longitudinal sides thereof having their edges inclined toward the rear end ofA the opening, the inclined portions coinciding with the upper surface of the cover 1 substantially on a line with the rear end of the opening 2. On this line, however, the metal of the rear end of the opening is upturnedpinto an inclined, transverse wall 4 which incliues at substantially the same angle as the in clined edges oi the side walls 'of the structure 3. |The wall 4L is secured along its edges to the inner face of the 'structure 3 so as to prevent the passage of any liquidrearwardly from the opening 2. The lower lon- ,gitudi'nal edges of the structure 3 where the latter are secured to the edges of the opening 2 are rolled outwardly and upwardly to form slideways 5, and these slideways 5 receive the legs 6 of a thumb piece or frame 7 which is shaped from a continuous length of Wire and is turned upwardly from its middle portions to also form a structure for a cover plate 8. Said cover plate 8 is secured to the lower side of the thumb piece 7 and is so formed that as the legs 6 are projected into the slideways 5 the cover is brought into seated position upon the edges o the wall or structure 3.

The edges of the cover 8 are shaped upwardly as at 9 so that the cover will seat inside o the edges of the wall 3, and the marginal portion will rest thereupon and furthermore the cover is made of resilient material which may be sprung slightly downwardly, as indicated in Fig. 2, below the extreme upper edge of the wall 3, so that when the cover is shoved into place, it will be caused to spring into position on the wall vand thereby securely held to its seat.

' From the foregoing description it is apparent that I have provided a practical and simple cover device for use upon cans containing liquids, or powdered or granulated materials, since the spout and its closure attachment can be practicably formed in any size to suit either the pouring of liquids, or broken or granulated products.

Furthermore the cover is so constructed that when slid into position it closes the spout opening entirely of its own resilience and therefore does not require the addition of any other locking device.

What I claim as myinvention is 1. The combination with a can top having a spout opening, of marginal walls surrounding three sides of the opening and havinfr their edges inclined toward the fourth si e, guide ways formed along the opposing walls, a guide element slidable in said guide ways and a closure element fitted to said walls and carried by said guide element to be seated by the latter when it is entered into theguide ways.

2. The eombination with a can fop having a spout opening, of a marginal element vertieally disposed around the opening, the

ends of the marginal element extending Vfreely into parallel relation and inclining toward the surface of the top, slideways formed alone' the parallel ends, a thumb piece havingllegs slidable in said slideways, and a closure carried by the thumb piece and shaped tofit on the edge of the marginal element when said legs are pushed into the slideways. Y

3. The combination with a can top having a spout opening, of a marginal element vertically disposed around the opening, the ends 'of the marginal element extending freely into parallel relation and inelining toward the surface'of the top, slideways formed along the parallel ends, and a closure having legs extending into said slideways, said closure being shaped to fit on the edge of said marginal element.

4. The combination with a can top having a spout opening, of a marginal element vertically disposed around the opening, the ends of the marginal element extending freely into parallel relation and ineljning toward Jthe surface of the top, slideways formed along the parallel ends, and a closure having legs extending into said slideways, said closure being shaped to fit onthe edge of said marginal element and having a resilient portion to cause it to snapon said edge.

5. The combination with a can top having a spout opening, of a marginal element vertically disposed around the opening, the ends of the marginal element extending into parallel relation and inelining toward the surface of the top, slideways formed along the parallel ends and a closure slidable into engagement with the edges of the marginal element and having a resilient lip to snap on said edge. Y

In testimony whereof, I affix my signature in the presence of two witnesses.

ROBERT POULSON.
